The term Large Greenhouse is used to describe a type of greenhouse that has a cross-sectional section of glass or plastic that provides the necessary atmosphere for the growth of large plants. In the earlier days, the term Large Greenhouse was used to define a type of greenhouse which was constructed in the shape of a large house or building.

The large greenhouses were constructed to enable the growing of huge trees and plants at a similar height to be possible. But now it has become possible to grow various other plants in the same greenhouse with the help of modern techniques.

Large Greenhouses are usually cylindrical and have an opening in the top. It should contain some type of air filter to keep the temperature of the air inside the greenhouse constant and to control the growth of pests also. It should have enough space to allow continuous air circulation.

All the plants and vegetables kept inside a Large Greenhouse need ample sunlight to grow healthy. So these greenhouses are mostly located above a tall building.

The history of Large Greenhouses can be traced back to the time when sunlight was discovered around the year the 1520s. Since the sun is the main requirement of plants, people started building large wooden sheds for a safe and adequate supply of sunlight.

These wooden greenhouses were later replaced by metal greenhouses. In recent years the plastic greenhouses are making huge advances as compared to the earlier types. Plastic Greenhouses can be easily used by anyone to grow vegetables, plants, or flowers.

The most important feature of Large Greenhouses is their insulation. They should provide proper insulation to the greenhouse to protect the plants from extreme cold or heat. The citation needed for this kind of greenhouse is the measurement of the greenhouse along with the details of the dimensions of the said greenhouse. The dimension of the greenhouse should be such that all the plants inside it get enough sunlight during the daytime. It should also be insulated properly.

One more thing that makes Large Greenhouses very economical is their energy efficiency. The contractors can save a lot of money due to the low cost of heating and cooling. Large greenhouses can be heated and cooled through the means of a polyethylene film system, electricity, gas, geothermal heat pump, wood, and coal. In this way, one can reduce the cost of heating and cooling by almost 50 percent.

Large greenhouses can be heated and cooled through the glass. Polyethylene film-based heating and cooling units are mostly used in heating greenhouses. The polyethylene film-based systems are very efficient and can even save a lot of money. A Large Greenhouse can be a great structure where plants can be grown effectively. If the owner uses a high-quality greenhouse he can grow a lot of plants and earn a lot of money.
